Heathrow T1 was opened by the Queen, T4 opened by their Royal highness the Prince and Princess of Wales (aka Charles and Diana if you're confused), not sure who was there to open T2, most likely the granny aswell.

We call it Gatport Airwick too!
Even from LHR you can seemingly hear the whining, not engines, but BALGW staff.
(All the £ we've poured into that place over the years, taking over BCal, then Dan Air, tried to make it work, sadly failed, listening to some of them you'd think it was all a plot by big, evil LHR)
Well, LHR is our home base, always has been.
